necessary.

Check the dimensioning of
the system. The
compensation power may
not be enough anymore or
the gradation of the stage
sizes is too rough or the
stage sizes may be
oversized.
Opposite control behaviour:
Controller switches on a
capacitor stage

COS-PHI
becomes more inductive instead
of changing towards capacitive.

Phases via the connection of
measuring voltage and
current do not correspond to
the set phase correction
angle

Connection of measuring
voltage and current has been
connected at a twisted angle
of 180° (U2 / U1 instead of
U1 / U2 resp. S2 / S1 instead
of S1 / S2).

Correct the connection of
current and voltage, if
necessary, or adjust the
phase correction angle.

If the connection of voltage
or current has been mixed
up, correct the connection
or add 180° to resp.
subtract 180° from the set
phase correction angle
(new angle < 360°) and
enter.
EXPORT and a COS-PHI
capacitive are shown on the
display, even though no active
power is fed back and the COS-
PHI is inductive.


Stage is defective

Check the capacitor stages;
fuse, capacitor or contactor
may be defective.

Set the stage type back to
“AUTO” after the cause has
been eliminated in order to
reset the alarm. The control
can use the stages again
for the control.
Stages are not switched on

Stages are too big

The necessary reactive
power is less than the
switching threshold of the
stage power of the smallest
capacitor stage.

Check
ΔQ in the
measurement value menu.

Check the dimensioning of
the system. The gradation
of the stage sizes may be
